Abstract: 247,615. Anderson, W., and Brown, W. Sept. 15, 1924. Vapour engines.- In heat engines of the type wherein the working medium is caused to oscillate by means of a displacer between cylinder ends maintained at a difference of temperature, the pressure of the medium being varied by a pressure-changing ram , as described, for example, in Specification 229,235, means are provided for varying the phase relation between the working and auxiliary rams. The means may consist of an adjustable coupling between the cranks of the rams, or a Stephenson link-motion may be employed. The phase relation may be varied in such a manner that the engine may be controlled, stopped and reversed thereby. The working medium may consist of liquid or liquid and vapour. In the adjustable coupling, Fig. 1, the crank shafts a<1>, a<2> of the working and auxiliary rams carry bevel wheels b', b<2> with which engage planet pinions c<1>, c<2>, the gearing being housed in a casing e. The pinions are connected, through cranks d<1>, d<2> and links f<1>, f<2> to a ring which can rotate in a casing h anchored by rods i<1>, i<2>. By displacing the casing h axially, the pinions c<1>, c<2> are rotated thus effecting a relative displacement of the shafts a', a<2>. In a modification the auxiliary ram is actuated bv means of a linkmotion and two eccentrics, the radius link being adjustable in the known manner by drag-links. The auxiliary ram may be actuated by a cam to produce a quick volume change. More than one auxiliary ram may be used with one working ram so as to make possible further variations in the algebraic sum of the displacements.

Abstract: 321,391. Dicker, S. G. S., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). July 27, 1928. Filaments.-Tungsten or other metal is coated with vanadium by heating to incandescence in an atmosphere of vanadium iodide so that vanadium is precipitated thereon. If the atmosphere is substantially free from impurities such as silicon, the vanadium produced is ductile. The tungsten &c. wire is suspended by leading-in wires from the neck of a sealed quartz vessel which is provided with a tube connected to a pump which removes air and any harmful gases produced during the reaction. Vanadium iodide or vanadium and iodine is then introduced in the vessel, which is heated to 800‹-1000‹ C., and the vanadium iodide, which is present or is produced, is dissociated, the vanadium settling on the wire. In a modification, a core-body is heated in an atmosphere of vanadium iodide and the vanadium-coated body is introduced into the reaction body with iodine. On heating the vessel, vanadium iodide is produced, and on further heating, dissociated, the vanadium being precipitated on a second core.

Abstract: 1406154 Dishwashers TAPPAN CO 8 May 1973 [11 Dec 1972] 21896/73 Heading A4F [Also in Division H2] In a dishwasher, the washing water is heated by contact with a jacket 25 containing transformer oil or other electrically non conductive liquid and enclosing the stator 70 and rotor 80 of a split phase induction motor 19, shaded pole or other motor which also drives an impeller 30 to force the water under pressure to distributing means 34 in the washing tub 10.The stator 70 comprises iron laminations circumscribed by windings, not shown, and the rotor 80 has apertures 85 therethrough. Thus, during motor operation, the heat generated in the windings together with that produced by eddy currents in the laminations heats the transformer or other oil which circulates within the jacket 25. Since the jacket 25 is in contact with the water travelling along a path indicated by arrows 26, the water is heated thereby. The water then travels through the rotating impeller 30 to a lower distributer means 34, as shown, or, if valve 60 is in an alternative position shown in phantom lines, to a higher distributing means (not shown) . A further valve 54 may direct dirty water to a drain. As the fluid in the jacket is heated it expands into an overflow housing 123. Alternatively, Fig. 2 (not shown) an enclosure comprising a flexible diaphragm may be situated adjacent the upper bearing housing 83 to allow fluid expansion.

Title: Improvements in or relating to apparatus for recording information on magnetic tape

Abstract: 982, 335. Local circuits for recording and playback. WAYNE KERR LABORATORIES Ltd., and J. MILDWATER. June 6, 1963 [June 6, 1962], No. 21958/62. Heading G5R. [Also in Division H3] Apparatus for recording on a magnetic tape 10 information represented by electrical signals 13 comprises two recording heads, 11, 12 recording two signals simultaneously on separate tracks on the tape, means for applying the signal to be recorded as amplitude-modulation on a first carrier of a given frequency, means for applying to one of the recording heads this amplitude-modulated carrier together with a constant amplitude reference signal, the reference signal being of the same frequency but in phase quadrature to the first carrier, and means for applying a carrier phase reference signal to the other recording head. The carrier phase reference signal is preferably the same signal as the constant amplitude reference signal. When playing back the signals, Fig. 2, the amplitude-modulated carrier and the quadrature carrier are picked up by head 21 and passed through amplifier 23 to a variable attenuator consisting of resistance 25 and bi-directional transistor 26. Phase sensitive detector 28 detects the amplitude of the quadrature carrier, using as a reference the quadrature carrier recorded on the other track and picked up by head 22. The output of detector 28 is compared in comparator 27 with a constant reference source 29, and the output of comparator 27 controls the resistance of transistor 26 so that the level of the quadrature carrier across it remains constant. This compensates for any spurious amplitude modulation applied to the signal by the tape recording and playback system. The signal is fed to a second phase sensitive detector 30, which is controlled by a signal derived from head 22 through a 90 degrees phase shifter 31, and the modulation signal is made available on lead 32. The attenuating network 25, 26 may be replaced by a capacitor in series with a voltagesensitive capacitor, such as a voltage sensitive diode, or may incorporate a directly or indirectly heated thermistor. In Fig. 3 (not shown) a thermistor is directly heated by the output of comparator 27 and is connected in the feed-back circuit of a high gain amplifier having the resistor 25 in series in its input circuit. An automatic warning device may be provided for giving an indication of any failure of the control system.
